Product Description

The SANDVIK COROMANT 5732590 is an indexable grooving and cutoff toolholder carrying the manufacturer catalog designation LF123F17-1616B-S. It is designed for external grooving, parting, and cut-off operations on CNC lathes and turning centers. The holder accepts N123F2-0250-CM inserts secured by a clamp-style insert holding method. It is configured for left-hand cutting and belongs to the CoroCut 1-2 series. The square shank measures 16 x 16 mm (0.63 x 0.63 inches), and the overall length is 125 mm (4.92 inches). Coolant-through capability is not supported. Machinists and CNC turning specialists working in production and job-shop environments install this holder.

This toolholder is suited for external grooving and parting applications on turned components in both production and jobbing environments. It handles groove widths ranging from 2.39 mm (0.094 inches) to 3.18 mm (0.125 inches) and supports a maximum depth of cut of 17 mm (0.67 inches). The CoroCut 1-2 platform is a widely used Sandvik Coromant system for grooving and parting operations, and this holder fits directly into that insert ecosystem using N123F2 series inserts.
